I am asking because I just realised the following
CoordinateReferenceSystem crs1 = CRS.decode("EPSG:27200");
CoordinateReferenceSystem crs2 = CRS.decode("EPSG:27200");
CoordinateReferenceSystem crs3 = CRS.parseWKT(crs2.toWKT());
assertTrue(crs1.equals(crs2)); OK
assertTrue(crs2.equals(crs3)); FAILS
The reason I came to this was because I was trying to make sure that when I am
reading data, it either
has projection information, or the user has to prompted for it.
If it doesn't, there is no way for me to know unless I check that
1. the crs is either null when reading of shape files
2. the crd is set to the "default" when ASCII grid files or georeferenced
images
What I found is that even if the .prj file is present in the latter case, the
statement
assertTrue(gc.getCoordinateReferenceSystem().equals(crs1)); (where gc is the
GridCoverage2D)
always returns false, even if the .prj file is that for EPSG:27200
So I suppose I have to look at the code to make sure I am indeed looking at the
same coordinate system?
Thanx
Gaby
